Specs At A Glance

Good To Know

Q: Will this throttle body work with the factory ECU? A: A 90MM throttle body typically requires a tune adjustment after install because the ECM compares blade position to airflow tables, so plan for calibration.

Q: Do I need new gaskets for installation? A: Reusing the old throttle body gasket risks air leaks, so fitting a fresh gasket during the swap is a smart step.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
